TUBBING MACHINE.

Application .filed August 25, 1925.

My invention relates to tumbling or tub-v purpose of polishing consisted of barrels rotatable on trunnions.

These were unsuited for operating on small articles, were slow in operation, diliicult to recharge, expensive to operate, stained the contents, and were difficult to clean. The essential objects of my invention are to avoid the above disadvantages; to enable the ready substitution of containers; to adapt the carrier to frames or holders of various sizes; to increase the polishing and smoothing eHiciency of the device; to insure accessibility of the containers; to enable'the simultaneous operation in a single machine of a plurality of containers, and to permit rotation of one container to be discontinued without effecting the operation of the other containers; and to attain these objects in a simple, strong, and compact structure. Other novel features will be hereinafter apparent.`

My invention consists in suoli parts and in suchA combinations of parts as fall within the scope of the appended claims.

ing mechanism. In the form thereof herein shown a hollow base comprises a front portion 16 and a rearwardly extending portion 17 disposed at right angles to the for-v ward portion. In the lportion 16 are webs or walls 18. Bolted to the forward portion of the base are one or more, in this instance two, standards 2() having bearings 22 for driven shafts 23. Bolted to the base portion 17 are supports 25 in which is journaled a driving shaft 27 having thereon a driving wheel or pulley 28 actuated from any convenient source of power. A sprocket wheel 30 on the shaft27 engages a sprocket chainy 32 which drives'a sprocket wheel 33 fast to a main shaft 34- rotatably mounted in openings 36 and 37 in the end walls of the base and in the webs 18 respectively. Fast to the main shaft 34 are sprocket wheels' 40 which through connections hereinafter ,detailed op erate the driven shafts 23.V

Upon one end of each shaft 23 is a carrieror bracket, indicated generally by, 45. This comprises a back 46 having a central external elevation'47 provided with a hole or socket'48 to detachably receive the end of shaft 23 engaged by a binding screw 49 or by friction, or otherwise. `Near one end of the back is a boss or shoulder 50 provided with a hole or socket 51 inclined with yrelation to the socket 48, and is adapted'to detachably receive the .shaft 23 if desired. In this case a set screw .52 is employed Vfor. this purpose. Integral with the other end of the backy 46 is a fiat horizontal supporting arm 53 upon which is fixed by a screw 54 a ,seat 55 comprising a disk 56 with a peripheral rim 57'.` A clamping plate 58 is attached to the opposite end of the back. This plate has a recess 59 in its rear port-ion adjacent whichis a perforation 60. At opposite sides of the recess the plate has lateral lugsGl `pivoted to the back 45 by pins 62; Integral with the forward end of the plate is a projecting handle 63. Adjacent thisa depending lateral lug 64 pivoted by pins 65 to upwardly directed klateral lugs 66 upon a cap 67 comprising a plate 68 and a depending peripheral flange 69. The member 67 is downwardly pressed by a spring 71 attached at one end through the perforation and fixed at its other end to a pin 72 in the back 15; also, by springs 74rattached at one end to pins supported by the sides of the plate 58, and attached at their other ends to pins 70 in the back 15.

A container or receptacle 7 8 iter the shot, powder, abrasive or cleansing material, as Well as l'or the articles to be operated upon, comprises a glass j ar or body 7 9 having upon its neck a rubber ring or gasket 81 upon which rests a glass top or cover 82 held in position by an ordinary Wire clamp 8d comprising a ring 86, bail 87, and operating loop 89.

TWhen the containers are arranged in series they are preferably disposed at different axial positions relatively to each other on their respective shafts 23; and in some instances the shatt 23 ol' one container is inserted in the socket 51, as shown at the left in Figure 1, rat-her 'than in the socket L18, as shown at the right in said figure. In some instances more thorough results are .secured by first mounting the socket 48 on the shaft 23, and next applying the socket 51 to the latter.

For the purpose of stopping any mechanical unit quickly, or for the purpose ot stopping one only of a series of cooperating units a clutch device is provided for each unit. In this case the clutch device is thus constructed. A collar 95 is lined by a pin 9? or otherwise to the shaft 23 adjacent one of the bearings 22 and is provided with longitudinal cavities 98, and With lugs 99 upon its inner end face. The slidable member 100 of the clutch is in the 'term of a cylindrical sleeve or body upon the shaft 23 provided in one end tace with cavities 101 adapted to register With the cavities 98, and With slots 102 adapted to slidably receive the lugs 99. The opposite end 'lace of the member 100 is provided with a cam shoulder 104- and with a lug 105. Guide pins 10T loose in the cavities 98 and 101 are surrounded with helical or expansion springs 108. rthese springs Whose ends enga-ge the end Walls oil the cavities tend to force the lug 105 of the mehr ber 100 into a slot 110 in the end tace ont a hub 111 oi a sprocket Wheel 112 upon which a sprocket chain 1111 is engaged and driven by one of the sprocket wheels l0, driven from the sha'tt 34.

The above described position 01: the clutch members, shown in ligure 8, is the normal, interengaged, or driving position enabling continuous rotation or the shaft Means, however,` are provided for throwing out or disengaging the clutch to enable the shaft 23 to come to rest at any desired instant. These consist, as shovvn in Figure 5, ot the following means. 11n upright lever 118 is pivoted intermediate its length upon a pin 119 in ears 120 upon the 'front face o1c each standard 20, the lovver portion of Which is preferably beveled as at 122. A hollow incase? horizontal cylindrical projection 12d integral with the rear 'face of the standard has bore vvith a portion 126 ot in cr ased diameter extending to the front tace o'j the standard. rllhe extension 124 has a hole 128 in its end. A. plunger 130 in the bore ot the extension has its end projecting through the hole and includes a head 132 in the enlarged portion vof the bore against which abuts one end of a helical spring 133 surrounding the plunger shank, and Whose opposite end presses against the end vv'all of the bore. llhe lower portionot the lever 118 is in contact with the head portion 132 of the plunger. A hand lever for Controlling the lever 118 consists of a handle arm 135 with an angular cam 136 upon its end. rllhe latter is pivotally mounted on a pin 138 in ears 139 upon the standard. rl'he cam has one face in engagement With the lever 118 to hold the beveled portion of the same against the tace et the standard against 'the pressure of the spring 133. ln, this position the upper end of the lever 118 is held away from engagement with the clutch mechanism. To throvv out the clutch the lever arm is manually depressed to the position shown in broken lines permitting the plunger 130 to 'torce the upper portion of the lever 118 into the path of the cam end 1011 and thus force the clutch meinu ber 100 towards the member 96 and Withdraw the lng 105 from its seat 110 tree et the member 111, in the position shown in Figure 7.

I claimz- 1. ln a tubbing machine, a driving sha-tt, a driven shaft, a bracket provided with a socket intermediate its length and with a socket inclined with relation to the first socket, both olsaid sockets being adapted to receive the end of the driven shaft, and a container mounted in the bracket.
